This invention relates to improvements in locomotive tenders, and has for its principal object to produce a new and improved construction and method of manufacturing .the

5 same, in which the lower portion of the tank body is formed ofan integralskeleton frame casting of sufficient strength to provldeun effect a main frame structure with interior baffle plates, the open portions of said casting beingthereafter finished by welding in relatively thin metal sheets to complete the bottom walls of the tank.- a

The invention may best be understood by reference to the accompanying drawings, in which of the bodybroken away,

- inga base casting adapted to form' -the main frame of a tender, and having, when.

completed, the upright end and side walls 11 and 12 of the tank body attached'thereto, so

that the baseecasting also forms a parto'f the i bottom of said tank. j 111 forming the casting- 10 a skeleton framework 'having suflicient' strength and rigidity isprovided, and the open portions of said frame "are thereafter closed by relatively lighter sheets of steel which are welded in place to complete the bottom of the tank. Details. of the base frame structure and welded-inf sections will now be described. :f g g The main casting .10 is best .'shown in Figures 3 and 4 before the welded-in sections are applied. In these figures'a hollow beam Figure l is a fragmentary side view of a finished tender body constructed n accord-- ance with my invention, wlth the upper parts Figure 2 is, a transverse section taken on 1927; emi. 208,141".

member extends longitudinally-of the center of the frame with suitable end-sills 21 and '22wand bolster supports-'17, 17, said beam member ispreferablyboxdike in-cross section, having side-walls, 23,23, upper wall 24 and lower wall 25, as is bestshown in the sectionsof Figures 2, 5, 6 and-7. In the form:

shown the center beam is widened at the forward end to conform with the shape of the coal compartmentvvhichis defined by the upright inner. walls 18, 18 (Figurefi) which connectwiththe main frame casting along lines-19,19,1showninFigure 4. A plurality of transversezbeams' are pro-f vided, including boxsection'beam 27 at the rearlbolster support 17 and another beam 28 attheifront bolster support of the tender. Other transverse members, suchasupright ribs 29, 29 mayalso' beeprovided. Diagonal braces 11 11" maybe connected to the transverse members to support theflside walls-12, 12 as shown. Inthe form shown, the transverse members 27, 28 and 29 form bafie plates to restrain excessive -1novement of the water in the tank, and may also beprovided with apertures, as for instance, aperture .29?- near the bottom of the tank,to permit passage of water between adjacenttankisections.

The outer marginof the base casting consistsof side members 30, '30., eachherein "con sisting ofla Vertical member 'witha rounded inturned flange 31.

- AsseeninEigures ,3 ands, the base is formed with openings-35, 35 between the- "centerbfeam 2,0,1 sidemembers:30, 3 0 and trans:-

yerse membersi27, 28 and 29; The marginal portionsof the frame about these openings are preferably provided with horizontally dlsposed flanges 36, 36 which are countersunk receivefiat steel plates 37, 37 in fitting en-I gagement therein.- These plates-are secured in place bywater-tight joints, preferably by slightly, as shown in Figures 2, 3 and 4, to

welding, as indicated in Figures 5, 6 and 7,

and thus form the bottom of thetank, Any other openings,

such as core holes, etc.,formed in the castingmay be closedin' a similar man- 7 ner, so that said casting g forms an integral part of the tank as, well V asthe mainframe V of'the tender, with its bolster support '17, 17

resting directly on the truck bolsters. This structure also eliminates the necessity for side sills, the side members 30,30 providing suggcient strength to supportthe sides of the ta 5 Although I have shown'and described certain embodiments ofmy invention, it will be understood that I do not vvish to be limited to the exact construction, illustrated and dem scribed, but that various changes and modifications may be made Without-dep arting from the spirit and scope of the invention. I claim: 1

1. In a tender, an integral castmain frame including longitudinal andtransverse frame members having openings therebetween, upright Walls connected to said members to form the sides of the tender tank, horizontally disposed fianged members surrounding said openings countersunk adjacent their margins,

and sheet metal pieces fitting in said countersunk flanges and Welded thereto to form With said mainframe casting the bottom ofsaid tank. g 2. In a tender, ,anintegral cast main frame including longitudinal and transverse frame members having openings therebetween, upright Walls conneotedto said members to form V the sides of the tender tank, and sheet metal pieces extending'across theopenings in said a casting adjacentthe bottom thereof to form \vith'the latter the bottom of said tank, said a longitudinal and transversemembers form ing upright baffles in said tank.

R5 '3. In a tender, an integral cast main frame ,o

including longitudinal and transverse frame members having openings therebetween, up right walls connected to said members to form I the sides-of the tender tank, and sheet metal 4 pieces extending across the openings in said casting"adjacent the-bottom thereof to form with thellatter the bottom oflsaid tank, -said longitudinal and'transverse members 'f orming uprightibaffi'es in said tank, andhaving 4.5 apertures adjacent "the bottom'of the'tank communicating between adj acent sides of-said Signed at Chicago, 111., this 12th day of} V e Ju y,"19'27. r P J v 5. p rm 5;) i CLARENCE B.
